Titanic | Pakistan

Flawed engineering and inadequate testing contributed to the catastrophic implosion of a private submersible during a 2023 expedition to the Titanic wreckage, the US National Transportation Safety Board said on Wednesday. Its report comes after a US Coast Guard investigation in August outlined a litany of issues with operator OceanGate’s conduct, as well as design flaws in its Titan submersible, that led to a “preventable tragedy” in which all five passengers were killed. “We found that OceanGate’s engineering process for the Titan was inadequate and resulted in the construction of a carbon fibre composite pressure vessel that contained multiple anomalies and failed to meet necessary strength and durability requirements,” NTSB’s report said. “Because OceanGate did not adequately test the Titan, the company was unaware of the pressure vessel’s actual strength and durability, which was likely much lower than their target. “Additionally, OceanGate’s analysis of Titan pressure vessel real-time monitoring data was...
